Tattersall (2007) has cautioned that the Lepilemur species reported by Louis et al. (2006), all diagnosed exclusively on genetic distance and all allopatric, be treated with extreme caution until supporting data are forthcoming.

Justification:
The extent of occurrence (EOO) of this speciescovers less than 10,340 km2. This geographic range is severely fragmented and undergoing continuing decline in area, extent and quality of habitat. The number of mature individuals is also known to be in decline. Based on these premises, the species is listed as Vulnerable.

This species is found in northeastern Madagascar. Known only from the Anjanaharibé-Sud region, ranging S of the Antainambalana River at least as far as the Fananehana River and including the Makira region. Additional surveys are needed to determine the northern and southern extents of the distribution (Louis et al. 2006). The extent of occurrence (EOO) is estimated to be less than 10,340 km2.

This species is listed on Appendix I of CITES. It occurs in Anjanaharibe-Sud Special Reserve and Mananara-Nord National Park. Based on its presumed distribution as understood here, it also would be the species in Marojejy and Masoala National Parks and Ambatovaky and Maratondrano Special Reserves. Further work is now urgently needed to clarify the distribution and taxonomic limits of the recently described Lepilemur species.
